| 40 | get a string |
| 41 | --[no-]string2 <str> get another string |
| 42 | --[no-]st <st> get another string (pervert ordering) |
| 43 | -o <str> get another string |
| 44 | --longhelp help text of this entry |
| 45 | spans multiple lines |
| 46 | --[no-]list <str> add str to list |
| 47 | |
| 48 | Magic arguments |
| 49 | -NUM set integer to NUM |
| 50 | + same as -b |
| 51 | --ambiguous positive ambiguity |
| 52 | --no-ambiguous negative ambiguity |
| 53 | |
| 54 | Standard options |
| 55 | --[no-]abbrev[=<n>] use <n> digits to display object names |
| 56 | -v, --[no-]verbose be verbose |
| 57 | -n, --[no-]dry-run dry run |
| 58 | -q, --[no-]quiet be quiet |
| 59 | --[no-]expect <string> |
| 60 | expected output in the variable dump |
| 61 | |
| 62 | Alias |
| 63 | -A, --[no-]alias-source <string> |
| 64 | get a string |
| 65 | -Z, --[no-]alias-target <string> |
